Abstract

The present disclosure pertains to shortening sleep latency during the wake to sleep transition. Sensory stimulation is delivered to a subject by sensory stimulators during a sleep session, and a measure of wakefulness of the subject is determined. The sensory stimulators are controlled based on the measure of wakefulness of the subject. The sensory stimulators may be controlled to modulate an intensity of the sensory stimulation delivered to the subject. For example, the sensory stimulators may decrease the intensity of the sensory stimulation as the measure of wakefulness decreases. The system then determines that the measure of wakefulness has reached stable sleep. The sensory stimulators are controlled based on the determination that the measure of wakefulness has reached stable sleep. The sensory stimulators may decrease the intensity of the sensory stimulation at a faster rate once the measure of wakefulness reaches stable sleep.

Claims16

Dependent claims

A system for controlling sensory stimulation delivered to a subject during a sleep session, the system comprising:

one or more sensors configured to generate output signals conveying information related to brain activity of the subject during the sleep session;
one or more sensory stimulators configured to provide sensory stimulation to the subject;
and
one or more processors coupled to the one or more sensors and the one or more sensory stimulators, the one or more processors configured by machine-readable instructions to:
determine, based on the output signals, a measure of wakefulness of the subject during the sleep session;
control the one or more sensory stimulators based on the measure of wakefulness;
determine, based on the output signals, that the measure of wakefulness has reached stable sleep;
and
control the one or more sensory stimulators based on the determination that the measure of wakefulness has reached stable sleep,
wherein the one or more processors are further configured to determine that the output signals comprise a noise level that breaches a threshold noise level, and
wherein, to control the one or more sensory stimulators based on the determination that the output signals comprise the noise level that breaches the threshold noise level, the one or more processors are further configured to cause the one or more sensory stimulators to deliver the sensory stimulation to the subject at a constant intensity.

8 more elements

A method for controlling sensory stimulation delivered to a subject during a sleep session with a system, the system comprising one or more sensors, one or more sensory stimulators, and one or more processors, the method comprising:

generating, with the one or more sensors, output signals conveying information related to brain activity of the subject during the sleep session;
determining, with the one or more processors, a measure of wakefulness of the subject during the sleep session based on the output signals;
controlling, with the one or more processors, the one or more sensory stimulators based on the measure of wakefulness;
determining, with the one or more processors, that the measure of wakefulness has reached stable sleep based on the output signals;
controlling, with the one or more processors, the one or more sensory stimulators based on the determination that the measure of wakefulness has reached stable sleep;
and
determining that the output signals comprise a noise level that breaches a threshold noise level,
wherein controlling the one or more sensory stimulators based on the determination that the output signals comprise the noise level that breaches the threshold noise level comprises causing the one or more sensory stimulators to deliver the sensory stimulation to the subject at a constant intensity.
